Abstract

Tanaman gedi (Abelmoschus manihot) merupakan salah satu tanaman yang berpotensi sebagai sumber antioksidan. Selama ini, ekstraksi daun gedi dilakukan dengan teknik maserasi sederhana sehingga kondisi proses optimum untuk pengembangan skala industri belum diketahui. Tujuan penelitian adalah mendapatkan kondisi optimum proses ekstraksi dengan menggunakan teknik maserasi. Penelitian dilaksanakan di Laboratorium Teknologi Agro Kimia, Jurusan Teknologi Industri Pertanian, Universitas Brawijaya, sejak Januari 2014 sampai Desember 2014. Rancangan percobaan menggunakan Central Composite Design (CCD), terdiri atas 20 run percobaan dengan 6 ulangan pada titik pusat (centre point). Analisis regresi dan keragaman dilakukan dengan menggunakan Software Design Expert Ver. 9.0. Trial. Setiap respon dari proses ekstraksi digunakan untuk mengembangkan sebuah model matematis yang berkorelasi dengan flavonoid total menurut persamaan polinomial. Selanjutnya ditentukan flavonoid total ekstrak daun gedi dan diuji aktivitas antioksidannya. Hasil penelitian menunjukkan kondisi proses optimum dengan menggunakan metode CCD diperoleh pada lama waktu ekstraksi 4,83 jam, suhu ekstraksi 34,33 oC dan kecepatan pengadukan 322 rpm dengan total flavonoid yang dihasilkan sebesar 55,41 mg g-1 serta aktivitas antioksidan dalam IC50 sebesar 383,49 ppm.

Abstract

Upaya untuk memecahkan masalah kerawanan pangan dan energi perlu segera dilakukan. Salah satu alternatif adalah mencari bahan baku yang dapat dimanfaatkan secara keseluruhan termasuk bagian-bagian yang selama ini dianggap sebagai limbah. Tanaman jagung (Zea mays) adalah komoditas pertanian yang sebenarnya punya prospek untuk dikembangkan produk-produknya secara luas, diikuti dengan upaya pemanfaatnya untuk menghasilkan produk olahan multiguna dengan bahan baku dari tangkai, daun, pelepah, biji jagung pipilannya serta bonggolnya. Rekayasa teknologi yang efektif dan efisien dapat diterapkan untuk menghasilkan produk pangan berbentuk ekstrudat termodifikasi dengan ubi jalar dan kedelai, pati jagung, dekstrose, sirup jagung, protein (gluten) dan minyak jagung. Tongkol jagung, disamping digunakan sebagai pakan ternak dapat juga dimanfaatkan untuk bahan baku sumber energi terbarukan antara lain bioetanol dan briket arang. Kulit jagung dapat diolah menjadi "soluble sugars". Batang jagung telah digunakan untuk bahan baku kertas. Selanjutnya dengan menggunakan mikroorganisme, daun jagung dapat diubah menjadi pakan ternak berprotein tinggi. Demikian juga jerami jagung dapat dimanfaatkan untuk pupuk organik atau kompos. Kebijakan pengembangan pertanian untuk komoditas jagung perlu didukung berbagai pihak terkait yaitu pengambil kebijakan, pengusaha dan petani, serta para peneliti, sehingga produksi produk multiguna berbasis jagung dapat lebih efektif dan efisien.

Abstract

Nipa (Nypa fruticans Wurmb.) belongs to the Arecaceae family, covering 30% of over 4 million ha of mangrove forest in Indonesia. The most valuable part of nipa is the fruits for food, drink, handicrafts, and medicine, leaving empty fruit bunches as waste. The empty fruit bunch waste reaches 75% of the total weight of nipa fruit, producing approximately 6 Mt/ha or over 6 million Mt in a year. Nipa empty fruit bunches (EFB) are biomass containing 27.3% lignin, 36.1% cellulose, and 21.8% hemicellulose. Due to Indonesia’s increasing nipa fruit harvesting, managing and finding a suitable solution to overcome waste issues is essential. In the present review, nipa EFB’s physical and chemical properties were found suitable as a biomass energy source. Nipa’s EFB energy recovery was potentially generated from direct combustion, pyrolysis, and briquette making. The harvesting challenge and emission from direct combustion or pyrolysis process limit the nipa utilization. Education and technology dissemination is required for the coastal communities to assist in utilizing nipa.

Abstract

Dates (Phoenix dactylifera) is a palm-type plant that belongs to the Phoenix genus, which widely grows in the Middle East and South Africa.  The use of date seeds was still limited.  Dates seeds contain high amounts of nutrient and bioactive compounds, such as fiber, phenols, and antioxidants. The microwave-assisted extraction (MAE) method could increase the extract yields in a shorter time and reduces the solvent volume. This research aimed to evaluate the optimal extraction time and material: solvent (w/v)  ratio. The response surface methodology (RSM) with the Central Composite Design (CCD) experimental design with two factors of extraction time (5 - 7 minutes) and the material: solvent ratio (1:10 - 1:50 (w/v)) was employed in this study. The responses were antioxidant activity (IC50), total flavonoid, and density. The results show that the optimum solution was an extraction time of 5.451 minutes and the ratio of material: solvent of 1:10 (w/v). This treatment produced dates seed extract with antioxidant activity IC50 of 28.406 ppm, total flavonoid of 2544.951 mg QE/g, and density of  0.886 g/mL. The  verification of the center point  was antioxidant activity IC50 of 27.849 ppm (98.04%), total flavonoids of 2573.723 mg QE/g (98.87%), and density of  0.8889 g/mL (99.67%), respectively.

Abstract

Pokak is a variant of the Madurese ginger drink made from spices. The main ingredient is ginger, while other additional ingredients are cloves, cinnamon, nutmeg, and masohi/masoyi wood. In general, these drinks are sold in liquid form. The maceration method was used to obtain pokak extract while spray dryer was used to obtain Pokak powder. Pokak is believed to boost immunity, increase stamina and warm the body. The development of Pokak Madura in powder form can increase the sale value, be more practical in the making and have a longer shelf life. This study aims to determine the optimal composition and conditions of Pokak microencapsulation. The parameters used are maltodextrin concentration (4.05; 5; 10; 15; 15.94%) and inlet temperature (120.27; 125; 150; 175; 179.7 oC). The optimization method used to get the best pokak powder was RSM (Response Surface Methodology). Tests at this stage were the total flavonoid test, antioxidant test, and morphology or best pokak powder profile using SEM (Scanning Electron Microscopy). Optimization results for the best treatment were a maltodextrin concentration of 10.639% and an inlet temperature of 148.042 oC resulting in a total of 6.447 mg QE/gram flavonoids and a percentage of antioxidants of 13.078%. The morphology of the particles is wrinkled with an average particle size of 5.372 µm. Thus maltodextrin as a coating or coating material with DE 10-12 cannot form spherical-shaped powder particles.

Abstract

Moringa leaves (Moringa oleifera) are a "Superfood" food ingredient rich in protein, phenolics, amino acids, and unsaturated fatty acids that benefit human health. Consumption in fresh form is prevalent, but the last decade has been plentiful in dry preparations. Pulse Electric Field (PEF) is one of the important preliminary treatments in drying vegetables and fruits. Electroporation on Moringa leaves is applied to determine the effectiveness and efficiency of drying on the leaves. The study aimed to determine the effect of PEF treatment before drying on the kinetics of drying and the microstructure of Moringa leaves. PEF treatment is carried out at voltages of 1000V, 1500V, 2000V and without PEF as a control. The treatment during drying was observed at the level of moisture content and effective diffusivity on each of the PEF and control treatments. Experimental data were entered into seven mathematical models and evaluated through Lewis, Page, Modified Page, Logarithmic, Two-term, Wang and Singh, and Simple exponential models. The results of the evaluation of the drying model were selected as the best drying mathematical model on the Logarithmic model. The highest diffusivity effective value at PEF with a voltage of 2000V of 3.25 × 10−9 m2/s. In the microstructure changes of Moringa leaves, the preliminary PEF treatment was conducted using the scanning electron microscope (SEM) test. Moringa leaves with pretreatment PEF 2000V color analysis was lightness (L*), redness (a*), yellowness (b*), and ∆E values of 41.74±0.34a, -8.64±0.28c, 20.16±0.94a, 7.08±0.53c. The results of moringa leaves extract with pretreatment PEF 2000V were total phenols and IC50 values of 55.60±1.24d mg GAE/gram and 76.79±0.77a ppm. Implementing PEF preliminary treatment on drying is expected to accelerate the drying process and maintain a decrease in the quality of the final product of Moringa leaves.

Abstract

AbstractMoringa leaves are a source of high antioxidants. This study aims to find an equation model for the extraction conditions of Moringa leaves with Pulsed Electric Field (PEF) pretreatment. Fresh Moringa leaves were treated with PEF in various voltages (1,000, 1,500, and 2,000 Volts), frequency (1,000, 1,500 and 2,000 Hz) and extraction time (4, 5 and 6 hours) as the factors studied. The best results and mathematical equation models obtained were determined from the extraction process. The parameters observed were yield, total phenolic compounds, and antioxidant activity. The Response Surface Method (RSM) was chosen to determine the equation model for the voltage, frequency, and extraction time combination. The results of ANOVA (Sum of Squares, Lack of Fit, and p-value) show that the model is adequate to present experimental data. The analysis results showed a significant value for total phenol in a quadratic equation, extract yields in a linear equation, and antioxidant activity in a linear equation. The model is presented in a 2-D contour graph and a 3-D response surface. The equation model shows that the best treatment is a PEF voltage of 2,000 Volts, frequency of 1,000 Hz, and extraction time of 4 hours.Keywords: antioxidant, equation model, moringa leaf, Pulsed Electric Field, Response Surface Method AbstrakDaun kelor merupakan salah satu sumber antioksidan yang tinggi.
